with a usual cone filer you might get off of ebay, do you gotta get a "activation kit" like that comes with k&n filterchargers??

the little oil stuff

 

thats only needed to clean the filter.....

 

and oil it

 

oh

well that answers it

why do they call it an activation kit

 

or do they call it an activation kit?

 

I believe that the oil, at least in the K&N does alot of the filtration. Many brands are designed not to use it, but I think those are mostly the ones that use foam filters, or SS.

you can buy the "activation" kits, and I'm sure it wouldn't hurt to use some on any intake that uses the paper type filter.
